Title: Manufacture of semiconductor device
Inventor: YAMAUCHI YUKIO
IPC: H01L29/06
Filed: 1987-01-09
Abstract: PURPOSE:To easily obtain a prescribed positive mesa structure during a simple process wherein a semiconductor substrate where a PN junction is formed is immersed in an etching solution and, at the same time, the semiconductor substrate is etched in such a way that a prescribed voltage is applied to a cathode and an anode of the PN junction. CONSTITUTION:An N layer 2 is formed on the main face of an N-type semiconductor substrate 1; a P layer 3 is formed on, its rear face. Then, an electrode 4 having a prescribed pattern and a wax layer 5 for blocking an etching process are deposited on both faces of the semiconductor substrate 1. Then, the electrode 4 on the side of the N layer 2 on the semiconductor 1 is made to function as an anode and is immersed in an etching tank 6. Then, a cathode 8 is immersed in an etching solution 7. By keeping this setup, a power supply 9 is connected to the anode and the cathode 8, and the semiconductor substrate 1 is etched. During this process, the semiconductor substrate 1 constitutes an N<+>-N<->P<+> structure; no electric current flows to the P<+> side due to a reverse bias; the etching speed is enhanced only on the side of the N layer 2. By this method, it is easy to, obtain a positive mesa structure 10 where the side of the N layer 2 has been etched at high speed.

Filed: 1990-01-12
Abstract: PURPOSE:To get rid of the intense fluctuation of tension in a strip and maintain a catenary form by setting up a control circuit so as to have acceleration or deceleration at the starting and stopping of a lift roll settled within the capacity limit of adjustable speed control over the strip. CONSTITUTION:When a connecting spot of a strip 4 comes to a protective territory for a backside coater 23, a command value is emitted by a position- speed commander 17 in accordance with a specified accelerating curve and an intermediate speed curve, through which an electric motor 6 is driven, thus a lift roll 22 is lifted up. Both accelerating and decelerating curves inherent in the commander 17 settles their speed variations to be produced at the starting and stopping of the lift roll 22 within the capacity of adjustable speed control over the strip 4 by a bridle roll 1 even in either case of up or down. Therefore any impact being given to a control system is checked and, what is more any variation in a catenary form due to intense fluctuations in tension of the strip 4 can be put down, thus the catenary form is maintainable.
